Summary of the invention
The objective of the invention is to propose a kind of safe and reliable sleeve assembly.
Purpose of the present invention will be achieved by the following technical programs:
A kind of sleeve assembly, comprise: relatively-stationary sleeve and overcoat, described sleeve is provided with a trachea, described trachea comprises a pore that is used to ventilate, the periphery of described trachea is arranged with one and connects the gas head, the described gas head that connects comprises a circular hole that can be connected with source of the gas, and the described gas head that connects can rotate relatively with described trachea, is provided with a usefulness between the two so that the on off mechanism of described pore and described circular hole UNICOM or cut-out.
Further, described on off mechanism is the kidney slot that is arranged on the described trachea, with be arranged on the described elongated slot that connects in a fit of anger, the pore of described kidney slot and described trachea is UNICOM all the time, described elongated slot and the described circular hole that connects the gas head be UNICOM all the time, when rotation is described when connecing the gas head and making described kidney slot and elongated slot UNICOM, described pore and circular hole UNICOM.
Further, the length of described elongated slot is greater than the length of described kidney slot.
Further, an end of described trachea is provided with the vent plug that is used to seal described pore.
Further, the described periphery that connects the gas head is arranged with a trachea cover, and the length of described trachea cover is greater than the length of described elongated slot.
Further, described connecing is provided with one in a fit of anger and is used to order about the described swing handle that connects the rotation of gas head.
Further, the periphery of described trachea is provided with a semicircle step, and the described periphery that connects the gas head is provided with a fan-shaped platform that cooperates with it.
Beneficial effect of the present invention is mainly reflected in: be used for UNICOM or cut off source of the gas swing handle structure and that the position is set is more reasonable than prior art, the doctor can not run in operation process, so just avoided the danger of having leaked gas in the operation, improved safety coefficient.

The specific embodiment
As shown in Figure 1, the invention provides a kind of sleeve assembly, comprise: relatively-stationary sleeve 1 and overcoat 2, described sleeve 1 is provided with a trachea 3, described trachea 3 comprises a pore that is used to ventilate 31, and the periphery of described trachea 3 is arranged with one and connects gas head 5, and the described gas head 5 that connects comprises a circular hole 51 that can be connected with source of the gas, the described gas head 5 that connects can rotate relatively with described trachea 3, is provided with a usefulness between the two so that the on off mechanism of described pore 31 and described circular hole 51 UNICOMs or cut-out.
Preferably, described on off mechanism comprises: be arranged on the kidney slot 32 on the described trachea 3 and be arranged on the described elongated slot 52 that connects on the gas head 5, the pore 31 of described kidney slot 32 and described trachea 3 is UNICOM all the time, described elongated slot 52 and the described circular hole 51 that connects gas head 5 be UNICOM all the time, when rotation is described when connecing gas head 5 and making described kidney slot 32 with elongated slot 52 UNICOMs, described pore 31 and circular hole 51 UNICOMs.
Preferred, the length of described elongated slot 52 is greater than the length of described kidney slot 32.When described trachea 3 inserts describedly when connecing in the gas head 5, can make described elongated slot 52 and described kidney slot 32 partially overlap by rotating the described gas head 5 that connects.
One end of described trachea 3 is provided with the vent plug 4 that is used to seal described pore 31, could be communicated with extraneous thereby make described pore 31 have only by described kidney slot 32.Described vent plug is that rubber is made, and described vent plug seals described pore 31 by the method for ultrasonic bonding.
The described periphery that connects gas head 5 is arranged with a trachea cover 6, and the length of described trachea cover 6 is greater than the length of described elongated slot 52, and described trachea cover 6 can be connected in the described periphery that connects gas head 5 by the mode of ultrasonic bonding.
